I am 19 years old and my chest looks little pointy? Will it be cured with time or it needs surgery?

Pectus Carinatum. Do a web search for pectus carinatum and it will go over the condition and treatment options.
No. You may have pectus carinatum or pigeon chest. It may or may not need be corrected. See a thoracic surgeon if you might want to be evaluated for surgical repair.
